HDRI is the abbreviation of “High Dynamic Range Image”, and in this case it is a 360ºx180º panorama. Its function is to provide you a real environment for your 3D work and make it the most realistic as possible.

Why should I get it?

This type of HDRI can be used for any 3D work as you wish. However the environment, and backplates have been thought for 3D car projects.

Isn’t it too low quality?

The resolution 5000×2500 pixels allows you to work with a good quality of reflections, and also with a manageable (.hdr) format on your 3D viewport. So, if you don’t have great computer power, you still can do realistic renders in an acceptable time and excellent quality.
Even more, for those users who need Higher Resolutions and are able to handle heavy (.hdr) images, this item also includes a 10000×5000 pixels panorama.
